Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a deep foundation pit lattice column cleaning device. Background Art

[0002] During the normal excavation and construction process of large deep foundation pits, a lattice column support system is usually adopted. After each layer of earthwork is excavated, mud and sand will accumulate in the lattice columns. If they are not cleaned up, it will cause safety hazards to subsequent operations in the pit and affect construction safety.

[0003] The conventional practice is for on-site workers to manually dig the soil, but since the height of each layer of lattice columns is generally about 6 to 8 meters, the operating height of manual soil clearing is limited, and it is often necessary to use a lifting vehicle or scaffolding to carry out soil clearing operations, resulting in low soil clearing efficiency. High-altitude operations pose a safety hazard to construction workers. On-site workers occasionally hit the lattice columns with hard objects to knock off the remaining soil, but this method is very likely to affect the structure of the lattice columns themselves.

[0004] The invention patent with authorization announcement number CN114351715B discloses a "deep foundation pit lattice column hollowing cleaning device and construction method", which mainly uses vibration to shake off the soil and then cleans up the soil and gravel through high-pressure water washing. The device does not require manual cleaning, but some soil and gravel are filled and compacted excessively, and vibration cannot shake off the gravel and soil. At this time, high-pressure water washing cannot clean up the gravel and soil in the lattice column, and manual secondary cleaning is required, which is time-consuming and labor-intensive. Moreover, the device can only clean the height of high-pressure water radiation. For lattice columns of other heights, the cleaning device still needs to be replaced to the washing position. The cleaning device is inconvenient to move, and the vibration will affect the strength of the lattice column, posing a safety hazard to the use of the lattice column. Summary of the invention

[0005] In order to overcome the deficiencies in the prior art, the utility model provides a lattice column cleaning device for a deep foundation pit, which is slidably connected to a movable trolley through a single-sided open slide rail vertically arranged on the side of the lattice column; a rotating head is arranged on the top of the telescopic rod at the bottom of the movable trolley; the rotating head is equipped with a brush and a stamping nozzle to first brush and then rinse the inside of the lattice column to clean the lattice column; the movable trolley slides up and down, and the entire lattice column can be cleaned without manual intervention, which saves time and effort, and has better cleaning effects by brushing and flushing, avoids affecting the strength of the lattice column, avoids manual climbing operations, and improves the safety of construction workers.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A deep foundation pit lattice column cleaning device, comprising a single-sided open slide rail and a movable trolley. The single-sided open slide rail is vertically arranged on one side of the lattice column. A clamp is arranged on the side of the single-sided open slide rail close to the lattice column, and the clamp clamps the lattice column. A slider is arranged at the bottom of the movable trolley, and a connecting shaft is arranged at the center of the slider. The slider is slidably connected by extending the connecting shaft into the opening of the single-sided open slide rail. The movable trolley slides up and down the single-sided open slide rail through the slider. An expansion rod is arranged at the center of the bottom of the movable trolley, a rotating head is arranged at the top of the expansion rod, a hard brush is wrapped outside the rotating head, and a punching spray head is arranged inside the rotating head.

[0008] Further, a lifting ring is arranged at the front end of the movable trolley, and the lifting ring is connected to a power traction device.

[0010] Further, the single-sided open slide rails are arranged in pairs symmetrically, and the openings of the single-sided open slide rails face outward.

[0011] Further, the sliders are arranged in pairs on both sides in the width direction of the movable trolley.

[0012] Further, the number of clamps arranged on one side of the single-sided open slide rail is not less than 2.

[0013] Further, the clamp clamps the lattice column through a fixing member, and nuts are arranged at both ends of the fixing member.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1) The device can adjust the opening degree of the clamp through nuts and fixing rods according to the exposed size of the lattice column, so as to adapt to the cleaning of sand and gravel inside lattice columns of different widths. It has a wide application range and strong practicability.

[0016] 2) The movable trolley is towed by a power traction device, and the moving direction of the movable trolley is restricted by the sliding connection between the slider and the connecting shaft and the single-sided open slide rail. The movable trolley can only move on the single-sided open slide rail, eliminating the need for manual high-altitude operation. The cleaning device does not require personnel to set up scaffolding or take a lift for high-altitude operation, and there is no need for repeated operation, improving the construction efficiency and ensuring the construction safety.

[0017] 3) During the cleaning process, a combination of a hard brush and a punching spray head is used for cleaning back and forth, which can ensure better cleaning effect, no cleaning dead angle, higher cleaning efficiency, and does not damage the overall structure and strength of the lattice column, providing better guarantee for the subsequent construction quality and construction safety of the project.

[0018] 4) The device has a fast cleaning speed, is convenient to adjust, simple to construct and easy to operate, greatly reducing the labor intensity of the operators, avoiding the potential danger of construction workers due to the falling of soil clods, preventing construction workers from accidentally sucking dust, improving the construction operation environment, and ensuring the physical and mental health of construction workers.

A movable trolley 7 slides up and down on the single-sided open slide rail 1. The telescopic rod 10 at the bottom of the movable trolley 7 extends into the lattice column 18. The rotating head 11 at the top of the telescopic rod 10 rotates, and the hard brush 12 on the rotating head 11 brushes the lattice column 18. The punching nozzle 13 inside the lattice column 18 sprays high-pressure water to wash the lattice column 18. The combination of brushing and high-pressure flushing cleans the lattice column 18 cleanly, with high working efficiency and good cleaning effect. It reduces the vibration impact between the lattice column 18 and the concrete support 19, improves the structural strength between the lattice column 18 and the concrete support 19, avoids high-altitude operations of construction workers, and improves construction safety.

[0029] As Figures 1-7 As shown in the figure, a deep foundation pit lattice column cleaning device includes a single-sided open slide rail 1 and a movable trolley 7. The single-sided open slide rail 1 is vertically arranged on one side of the lattice column 18. A clamp 3 is arranged on the side of the single-sided open slide rail 1 close to the lattice column 18, and the clamp 3 clamps the lattice column 18. A slider 8 is arranged at the bottom of the movable trolley 7, and a connecting shaft 9 is provided at the center of the slider 8. The slider 8 extends into the opening 2 of the single-sided open slide rail 1 through the connecting shaft 9 to achieve a sliding connection. The movable trolley 7 slides up and down on the single-sided open slide rail 1 through the slider 8. The connecting shaft 9 of the slider 8 is arranged in the opening on one side of the single-sided open slide rail 1. Restricted by the opening 2, the connecting shaft 9 can only slide up and down, and the slider 8 on the connecting shaft 9 can only drive the movable trolley 7 to slide vertically on the single-sided open slide rail 1. A telescopic rod 10 is arranged at the center of the bottom of the movable trolley 7, and a rotating head 11 is arranged at the top of the telescopic rod 10. The outside of the rotating head 11 is wrapped with a hard brush 12, and a punching nozzle 13 is arranged inside the rotating head 11. The telescopic rod 10 can freely extend and retract, and the rotating head 11 is extended into the lattice column 18 to clean the inside of the lattice column 18 through the brush 12 and the punching nozzle 13.

[0030] Further, a lifting ring 14 is arranged at the front end of the movable trolley 7, and the lifting ring 14 is connected to the power traction device 17.

[0031] Further, a high-pressure water tank 6 is arranged behind the movable trolley 7. The high-pressure water tank 6 is connected to the punching nozzle 13.

The clamp 3 is a clamping member that fixes the single-side opening slide rail 1 to the lattice column 18. In order to ensure that the single-side opening slide rail 1 is vertically fixed to one side of the lattice column 18, at least two clamps 3 are required to clamp the lattice column 18 on both sides.

[0035] Further, the clamp 3 is connected by a fixing member 4 to clamp the lattice column 18. Nuts 5 are provided at both ends of the fixing member 4. The nuts 5 adjust the distance between the clamps 3 between the fixing members 4, thereby adjusting to clamp lattice columns 18 of different widths, and the cleaning device has a wide range of applications.
